Explaining that the purity and simplicity of the tranquil soul are disturbed by thoughts, just as (when) you write or depict anything on the surface of a mirror, though you may (afterwards) obliterate it entirely, (yet) a mark and blemish will remain (on the mirror).

روی نفس مطمنه در جسد ** زخم ناخنهای فکرت می‌کشد

The face of the tranquil soul in the body suffers wounds inflicted by the nails of thought.

فکرت بد ناخن پر زهر دان ** می‌خراشد در تعمق روی جان

Know that evil thought is a poisonous nail: in (the case of) deep reflection it rends the face of the soul.

تا گشاید عقده‌ی اشکال را ** در حدث کردست زرین بیل را

In order that he (the thinker) may loose the knot of a difficulty, he has put a golden spade into ordure.
